3 Applications

Together with the multifrequency receiver US-1000D
from JTS, this multifrequency pocket transmitter
makes up a wireless audio transmission system. For
adjusting the transmission frequency, two modes are
available to ensure maximum flexibility:
1. In the group mode, the unit operates with four
transmission groups (A – D) to which 16 transmis-
sion channels are assigned respectively, i. e. alto-
gether 64 factory-set transmission channels are
available. These channels in the UHF range of
790 – 814 MHz can be selected as desired.
2. In the frequency mode, the transmission frequency
within the UHF range of 790 – 814 MHz can be se -
lected as desired (frequency spacing 25 kHz).
The pocket transmitter is supplied with the Lavalier
microphone CM-501. Instead of the CM-501, it is also
possible to use e. g. the headband microphones
CM-204... and CX-504 or the instrument microphones
CX-508W and CX-516W from the JTS product range.
